1 Product Warranty 1.1 In the case of purchase from a supplier other than NPM If your device was purchased from a supplier other than NPM, please contact that supplier. 1.2 Warranty period The warranty period is one year from the date of delivery 1.3 Warranty scope If defects are found in the product during the warranty period under normal use as described in this document, NPM will repair the product without charge. However, the following cases are not covered by the warranty and free repair does not apply to the product even during the warranty period. The Products are modified or repaired by anyone other than NPM or an authorized repair facility. The defect results from abuse or mishandling of the product. Wearing of components, natural deterioration or fatigue (motor axle bearing, gear, grease, cables, etc.) The defect results from any use other than original use. The product has been subjected to natural disaster or force majeure such as fire, earthquake, lightning strike, wind and flood, salt, and electrical surges. The defects or damage results from the cause other than the fault of NPM. 1. NPM will not provide on-site repair. All products to be repaired must be sent to NPM or an authorized repair location. 2. The warranty period of the repaired product does not extended beyond the warranty period of the product before the failure. It is the same as the warranty period of the product before the repair. 3. This warranty covers the product. It does not cover damages caused by the product s defects, etc. 4. A replacement may be provided instead of a repair at the sole direction of NPM. This documents aims to describe the function of the product and it does not warrant fitness for a particular purpose. The application examples and circuit diagrams in this manual are described for your reference. Please confirm the feature and the safety of device or equipment before use. Please do not use this product for the following types of applications. If you plan to use the product as described below, please contact our sales department. Any equipment that may require high reliability or safety, such as nuclear facilities, electricity or gas supply systems, transportation facilities, vehicle, various safety system, patient critical medical equipment, etc. Any equipment that may directly affect human survival or property Usage under conditions or circumstances that are not specified in the brochure, manual, etc. When this product is used in any equipment where faults or malfunctions may directly affect human survival or property, please secure high reliability and security with redundancy design, etc. 2
2 General The AD1131 is a constant voltage stepper motor driver for 2 phase unipolar stepping motors. The maximum output current is 1.1Amps per phase. 3 Specifications 3
3.1 Notes 1. It is recommended that the motor input voltage (VM) be connected after turing on the logic (VCC.) When powering the unit off, it is recommend that you disconnect VM first, followed by VCC. When disconnecting VCC, large currents may be allowed to flow that could otherwise damage the motor. 2. All input pulse signals must last 10 microseconds or more. After commanding a change in Direction, or Full/Half step mode, 10 microseconds must elapse before sending step commands. 4 Block Diagram 4

5.5 LED Function LED1 and LED2 are lit under the following conditions: LED1 is green with logic power (VCC) is supplied. LED2: When the motor is rotating, LED2 will flash. 6 Connections 6.1 Power Supply Connection CN1 Power supply connector (compatible connector type: IL-G-4P-S3T2-SA) Pin Pin Name Pin Description 1 VM Power supply input for motor (VM) 2 GND Ground 3 +5V Power supply input for driver logic (VCC) 4 GND Ground 6.2 I/O Connection CN2 I/O connector (compatible connector type: IL-G-8P-S3T2-SA) Pin Pin Name Pin Description 1 CW/CLK CW signal input in 2 pulse mode, CLK input in 1 pulse mode 2 GND Ground 3 CCW/DIR CCW signal input in 2 pulse mode, DIR input in 1 pulse mode 4 GND Ground 5 FULL/HALF Full Step (2-2 phase excitation) or Half Step (1-2 phase excitation) 6 MTR OFF Input to enable/disable the motor 7 +5V Driver logic power input (Internally connected to CN1 pin 3) 8 GND Ground 6.3 Motor Connection CN3 Motor connector (compatible connector type: IL-G-6P-S3T2-SA) Pin Pin Name Pin Description 1 COM Common wire connection for phase A and B (Internally connected to VM) 2 COM 3 A (phase 1) Motor A phase connection 4 /A (phase 3) Motor /A phase connection 5 B (phase 2) Motor B phase connection 6 /B (phase 4) Motor /B phase connection 6
7 Handling Precautions 1. This driver is a natural cooling type. Put this product in a well-ventilated place and provide at least 10mm clearance around this driver. 2. Do not use in a place with dust, oil mist, corrosive gas, etc. Additionally, remove dust periodically. 3. Do not put this driver in a place with excessive vibration and direct physical shock. 4. Make sure to keep the signal line (CN2), the power line (CN1) and the motor line (CN3) away from one another to prevent electrical noise. 5. If there are noise sources such as relays, high-pressure switching equipment or inverters, these may cause induced and radiation noises in the signal lines or power lines and may cause malfunctions. Make sure to keep the wires and driver as far away from such noise source as possible. 6. Ensure that STEP input signals are Logic High (Logic low when not signal is being sent.) Reversal of logic polarity may cause malfunctions and cause the motor to misstep. 7. Be careful when touching metal parts. The metal parts may have sharp edges. 8. Do not touch the board of this product while the power is supplied. When moving, wiring, or performing maintenance, power this product off. 9. Be careful if you touch the product while the power is supplied and just after the power turns off. The product may be hot. 10. Keep this driver out of reach of children. 11. Store this driver in a place with the predetermined range of temperature and humidity. Do not leave it in a place subject to direct sunlight. 12. Plug in the connectors carefully. Do not insert and remove connectors with wet hands. 13. If smoking, abnormal odor or noise occur, shut down the power immediately. 7
